Randomized Controlled Trial Multicenter Study Comparative StudyThe management of acute hypertension in patients with renal dysfunction: labetalol or nicardipine?
To compare the safety and efficacy of U.S. Food and Drug Administration (FDA)-recommended doses of labetalol and nicardipine for hypertension (HTN) management in a subset of patients with renal dysfunction (RD). ⋯ Within 30 minutes of administration, nicardipine is more efficacious than labetalol for acute blood pressure control in patients with RD.

Randomized Controlled Trial Comparative StudyComparison of subjective effects of extended-release versus immediate-release oxycodone/acetaminophen tablets in healthy nondependent recreational users of prescription opioids: a randomized trial.
Prescription opioids have substantial abuse potential. This study compared the positive subjective drug effects of a newly developed extended-release (ER) oxycodone (OC)/acetaminophen (acetyl-para-aminophenol [APAP]) formulation with those of immediate-release (IR) OC/APAP. ⋯ This phase 1 study conducted in the United States was not registered.

Review Case ReportsCombining opioid and adrenergic mechanisms for chronic pain.
Chronic pain is a highly prevalent medical problem in the United States. Although opioids and serotonin-norepinephrine reuptake inhibitors (SNRIs) have demonstrated efficacy for relief of chronic pain, each has risks of adverse events in patients. Because of the risk of opioid abuse and addiction, combinations reducing opioid requirements are particularly valuable. ⋯ A number of factors affect whether specific combinations have additive, synergistic, less than additive efficacy, or increase adverse events in patients, including general pharmacokinetic considerations, the potential for pharmacodynamic drug interactions, dose, and timing. Because there is little clinical evidence guiding combination therapy with separate opioid and SNRI agents, using single-molecule agents provides safe and effective therapy and should be the first option presented to patients. The use of empiric combinations of separate opioid and SNRI combinations needs to be considered in light of clinical cautions, including the lack of published evidence to guide dose conversion from any opioid to tramadol or to tapentadol, and vice versa; the need to avoid combinations with known drug interactions; and the need to titrate the dose when adding an SNRI to an opioid, and vice versa.

Acute pain: effective management requires comprehensive assessment.
Pain is among the most common reasons that patients seek medical care, and inadequate assessment may result in suboptimal management. Acute pain in response to trauma or surgery can be complex, variable, and dynamic, but its assessment is often simplistic and brief. One-dimensional rating scale measures of pain severity facilitate rapid evaluation and often form the basis of treatment algorithms. ⋯ Increased efforts and research are necessary to enhance the utility of available acute pain assessment tools. Developing more comprehensive tools for patient assessment is the first step in achieving the ultimate goal of effective acute pain management. The objectives of this review are to summarize issues regarding the complexity of acute pain and to provide suggestions for its evaluation.

The economic burden of diagnosed opioid abuse among commercially insured individuals.
The abuse of prescription opioids imposes a substantial public health and economic burden. Recent research using administrative claims data has substantiated the prevalence and cost of opioid abuse among commercially insured individuals. Although administrative claims data are readily available and have been used to effectively answer research questions about the burden of illness for many different conditions, an important issue is the reliability, replicability, and generalizability of estimates derived from different databases. ⋯ Although the prevalence of diagnosed opioid abuse was higher than reported in the original analysis, the trend of increasing prevalence over time was consistent across analyses. Additionally, diagnosed abusers had excess annual per patient health care costs of $11,376 in the replication analysis, which was consistent with the excess annual per patient health care costs of diagnosed abuse of $10,627 reported in the original analysis. The replication analysis also found an upward trend in the prevalence of diagnosed opioid abuse over time and substantial excess annual per patient health care costs of diagnosed opioid abuse among commercially insured individuals, suggesting that these findings are generalizable to other commercially insured populations.
